Vehicle Communication Network Path Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication networks for vehicles face challenges in rural areas and isolated regions due to limited mobile radio coverage and restricted range of direct wireless connections, making it difficult to collect information reliably and over a larger area.
Innovation Solution
A method where a motor vehicle transmits a request message to outside vehicles, which relay response messages with current positions, allowing for the determination of a communication network plan and defining a unique transmission path for additional requests, using wireless radio links like WLAN or car-to-car standards to extend coverage beyond mobile radio limitations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mobile radio links are used for vehicle communication, then communication coverage is provided, but the system fails in rural regions or isolated areas where mobile radio coverage is insufficient
Solution Approach 1:
The patent introduces intermediate vehicles as relay nodes that forward communication signals between the requesting vehicle and distant target vehicles. These intermediate vehicles act as mobile routers, extending the communication range beyond the limitations of direct wireless connections and mobile radio coverage, thereby enabling reliable communication in rural or isolated areas where traditional infrastructure is unavailable.
2Reliability
If direct wireless connection between vehicles is used, then information exchange is enabled, but the communication range is greatly restricted
Solution Approach 1:
The patent segments the communication path into multiple hops by introducing intermediate vehicles. Instead of requiring a direct wireless connection between the requesting vehicle and the target vehicle (which would be limited to close proximity), the communication is divided into sequential segments: requesting vehicle → intermediate vehicle → target vehicle. This segmentation enables information exchange over much greater distances by chaining multiple short-range wireless connections together.
3Area of stationary object
If a communication network is established using multiple outside vehicles, then information collection coverage is extended, but the system complexity increases
Solution Approach 1:
The patent implements self-service mechanisms where intermediate vehicles automatically forward received signals to appropriate target vehicles without requiring centralized control or complex network management. The system leverages the autonomous capabilities of individual vehicles to relay communications, and the requesting vehicle receives responses aggregated from multiple sources, thereby extending coverage area while keeping the management complexity relatively low through decentralized operation.

AI summary
The invention relates to a method for determining a communication network for collecting information in the surroundings of a motor vehicle, in which a request message is transmitted, and the request message is received by a first outside vehicle, and a first response message is transmitted by the outside vehicle to the motor vehicle, wherein the request message of each first outside vehicle is transmitted to at least one respective second outside vehicle, wherein a second response message is transmitted by means of the respective second outside vehicle to the first outside vehicle and from there is transmitted to the motor vehicle, wherein a current position of the respective outside vehicle is transmitted with the response messages, and wherein, depending on the response messages, a network plan of the communication network is determined by the motor vehicle, and on the basis of the network plan, a unique transmission path to one of the outside vehicles is established for another request message of the motor vehicle for collecting information from one of the outside vehicles.
